  • Publication number: 20030082965
    Abstract: a control unit is provided for closing the throttle when the engine has been rotated for more than a prescribed time period at more than a prescribed number of revolutions, and the throttle has been opened for more than a prescribed time period at more than a prescribed opening. The control unit increases the number of engine revolutions to a predetermined number of revolutions irrespective of the throttle and maintains the same for a predetermined retention time when the steering handle is turned to the left or the right by more than a prescribed angle. The time to start controlling the number of engine revolutions may be delayed by providing a delay time for delaying the time to start controlling the engine revolutions. The number of engine revolutions may be controlled after the hull is underwater. As a consequence, the amount of sideslip of the jet propulsion boat can be improved.

  • Patent number: 6428371
    Abstract: A watercraft with a steer-responsive speed controller generates thrust when the steerable propulsion unit is turned beyond a predetermined angular threshold. Turning the steering wheel beyond the threshold causes the speed controller to increase engine speed so that the propulsion unit produces thrust at least equal to the minimal propulsive force needed to effectively steer the watercraft. This system ensures that there is always sufficient thrust for steering the watercraft. This system is applicable to single-engine personal watercraft, twin-engine jet boats or motorboats equipped with swivel-mounted outboard motors. In one form of the system, rotation of the steering wheel beyond the angular threshold causes an actuating cable to open the throttle to increase engine speed. Alternatively, an electronic control system regulates the engine by calculating the optimal power settings based on measurements derived from a speed sensor, a steering angle sensor and, optionally, a throttle position sensor.

  • Patent number: 6085684
    Abstract: A trim tab control apparatus includes a switch housing that mounts to the lever of a throttle of a boat. The switch housing provides a socket that holds a dual trim tab switch arrangement in front of and below the handle of the throttle. This enables a pilot of a boat to operate either or both of the switches that control the port and starboard trim tabs. The pilot of the boat can operate either trim tab by depressing a selected of the switches or both trim tabs can be raised or lowered at the same time by operating both switches at the same time with one finger, wherein typically only the index finger of the pilot is required. The apparatus of the invention enables the operator of a boat to operate both port and starboard trim tabs without even having to view the switches because they are in such close proximity to the user's index finger while the pilot is driving the boat, holding onto the throttle.

  • Patent number: 6086435
    Abstract: The present invention is an ignition control system for an engine having an ignition system. The ignition control system is arranged to determine if a speed of the engine is decreasing at greater than a predetermined rate, and if so, to initiate an ignition timing compensation mode in which target engine speeds during the time of deceleration are set. These target engine speeds are compared to the actual engine speed and a firing timing of the ignition is advanced if the actual engine speed is less than the target speed and the firing timing of the ignition system is delayed if the actual engine speed exceeds the target speed.
